Introducing Speed Channel - We coupled the concept of a large, fast, unsupported face and matched it with an innovative idea called Speed Channel. This engineered trench runs across the sole of the club and around the perimeter of the back cavity. It minimizes face thickness for a more pronounced flex and recovery on impact. This enhanced trampoline effect increases ball speeds across the face to deliver greater distance without sacrificing feel.
Deep Perimeter Undercut - Fly-Z Irons feature our deepest undercut yet to create the largest unsupported face COBRA has ever offered, meaning you get extreme distance on center hits and consistent distance on off center hits. Speed Channel takes that responsive face to the next level.
Harmonic Cavity Insert - With all that speed in mind, we placed an engineered Thermoplastic Urethane insert right behind the impact zone to damp vibrations and ensure greater feel.
The Fly-Z Irons feature COBRA’s revolutionary Speed Channel technology – a visible trench positioned on both the cavity behind the face and on the sole of the irons designed to flex and recover at impact to deliver great distance through faster ball speeds. The irons modern head shape combined with the Speed Channel delivers higher speeds across the face and yields the best combination of distance, forgiveness and feel. The remarkable feel comes from the harmonic cavity insert that includes an engineered Thermoplastic Urethane insert positioned directly behind the impact zone for vibration damping and improved feel at impact. Combine this with extremely deep cavity undercutting and heel and toe weighting (Zone Weighting Technology), and the Fly-Z irons are true game-changers.
